Which embryonic stage is a ball-like mass of 16-32 cells produced by mitotic divisions of the zygote?

Explanation:
Cleavage after fertilization produces a solid ball of cells called the morula, typically with about 16–32 cells. The zygote is the single fertilized egg before divisions begin. The morula forms before the hollow-blasted stage known as the blastula, which has a fluid-filled cavity, and later gastrulation leads to the gastrula with germ layers. So the ball-like mass of 16–32 cells produced by mitotic divisions of the zygote is morula.
